Subaru - Outback :: Low Humming Noise Started At Around 40 MPH Or So - Front Engine Cowling
Mar 13, 2014
I noticed a low humming noise lately on my wife's 2007 Outback which started at around 40 MPH or so. I thought it might be something with the added roof rack attachment or tires which are Michellen Rain Force tires installed about a year ago. It sounds like an aerodynamic issue to me. Nothing has changed on the roof racks and the tires show no sings at all of unusual wear.
I looked in front of the vehicle and underneath to see if I could see something and noticed the cowling immediately under the exhaust manifold and where I removed the small door for frequent oil changes is bowed down in the rear creating a scoop which I think is the humming noise. I am trying to find the darn door in the garage so I can re-install it, but it got me thinking, is the whole cowling even necessary to have under there?
I know it can prevent rocks and things from hitting the underside of the engine, but is it really more for simply aerodynamics? It is a pain sometimes working underneath because it blocks access to everything. I was thinking of simply removing the entire contraption.

2009 Subraru Impreza Outback Sport (60K miles).. I'm trying to figure out what's wrong with my clutch. When I start my car I hear a squealing noise from the engine that sticks around until my car is warmed up. If I depress the clutch while it's warming up (and squealing), it goes away. Bearing?

I thought it was the tired due to the cold weather. But now it is warmer the noise is still there. Bareknuckes previously mentioned wheel bearings as a potential problem. The car is driving (sound-wise) like I have some huge mud-bogger tires on or like crossing a cattle-guard continuously. so loud (in the cabin) that sometime I forget to shift because I hear the humming rather than the engine.

My 2002 outback tape deck, which I use primarily to listen to my phone via a cassette adaptor, has recently started making a very loud buzzing/humming noise. It does this with both my old and a new adaptor, as well as a standard audio tape.
I could try using a head cleaner on the tape deck, but my impression is that this isn't what typically would happen if the head needs cleaning, and I don't particular want to waste the time and money on a solution that I'm pretty sure isn't going to work, but I'm asking you all in case you know better than me (a real possibility). I just don't know if I should try that first, or if I should just go out and purchase a new car stereo that has either blue tooth, or an audio input plug so I can directly plug the phone in that way.
Also if I do go the way of replacing the stereo, is that generally a straightforward process? And would most replacement stereos be compatible with my vehicle, or do I need to be selective?

I have a 2002 Subaru Outback that recently started making an odd noise. This noise is somewhat hard to describe, but sort of sounds like "urrh ah urrh ah" almost like a rubbing noise or a deep squeak (not high pitched). This noise only occurs when I'm braking, starts when I'm slowing down (going below 20 mph) and becomes more pronounced as I reach a full stop. The noise starts out fast (urr ah urr ah urr ah) and slows down as the car slows down (and gets louder as I come to a complete stop. It is more pronounced when I'm braking going down a hill (louder than when I'm stopping on a flat surface). It does NOT do it when I'm braking in reverse, or when I'm braking going up a hill. You also cannot hear the noise outside the car- only inside the cabin.

2005 Subaru Outback XT 2.5 ... We were driving yesterday and the car started making a whirring noise as I accelerated. No noise wen not pushing on gas. Then, the noise mostly went away. Then we heard a rattling noise. Sounded like it was near the front passenger tire. After about another 10 minutes, the check engine light went on and the cruise control was disabled. On our way home (after we stopped to ski), the rattling wasn't so loud, car seemed to be driving fine, but CEL is still on. deas what this might be? Is it safe to drive it about 15 miles to the closest AutoZone to get the code? Or straight to an independent shop?

I am about to buy a 2003 Subaru Legacy Outback Sedan H6-3.0. When it gets up to about 40-45mph it begins a low hum or moan and gets louder as it goes faster. At freeway cruising speed the whole car is moaning with what I would describe as a mild vibration. My first inclination is to think it is a wheel bearing issue.My wife thinks it might be a tire issue. She said she remembers the friend that we might buy it from saying that she had replaced two of the tires on it. I know that on all wheel drive vehicles you have to replace all 4 tires at the same time. Could that cause a sound like this? If so how long might it take to cause damage to the drive system with different size tires?

This is a question about a Subaru Outback, but probably pertains to many other cars as well. I have a 2006 Subaru Outback with 112K miles. I bought new tires for it in May 2012, and in September 2013 I started to notice a low humming/buzzing sound while driving. I looked online and came up with 2 options - either the wheel bearings or the tires. Because the sound changed pitch depending on the road surface, I thought it must be the tires. I took it in for an oil change and had the mechanics check the bearings. They said the bearings were fine, but the tires were cupping and feathering badly because I hadn't rotated them, and that was the source of the noise.
I had them rotate the tires and do an alignment and went on my way. The sound slowly got worse - it peaks at ~65 MPH and then changes pitch above 70 MPH and is not so bothersome - and I started to lose gas mileage ( 4-5 MPG). On Dec. 30, 2013 I took it in for the next oil change and bought brand new tires - Bridgestone Turanza Serenity designed for quietness - and had them do an alignment, and drove away only to find that the noise is still there and I still have lousy gas mileage.
My next thoughts were the transmission or the catalytic converter, but since the noise doesn't change when I take my foot off the gas or put it in neutral I don't think it is either one of those. The alignment showed that the Caster on both front tires is off, but since both tires are off by roughly equal amounts I was told that this is not something to worry about. I do occasionally notice some vibration while driving or while idling, but it is intermittent and I don't think it has anything to do with the noise.

I just replaced both front strut mounts on my 2005 Outback 3.0L. I was 100% sure that it would resolve an ongoing noise/rattle in the front end when driving over bumps and generally rough roads. It worked with some of the noise because the strut mount bearings were shot. But much to my disappointment after putting everything back together I still have a rattle (more like the sound when you shake a shoe box with a tennis ball inside it) in the right front suspension somewhere. When lifted the right front wheel is solid with no wobble left to right or top to bottom so I"m thinking it is not a tie rod but I am not a professional mechanic. Should I take the right front strut back off and check the new mount or is there an easier answer.

I have a 1996 Subaru Outback. There is a strange noise emanating from the center/front of the car. It only occurs when I stop accelerating over the speed of 50 mph. It sounds like a combination of a marble rolling around in a coffee can and a baby rattle. No sound at lower speeds or when I accelerate.

I bought a new 2011 Outback about 3 weeks ago, and I have around 1500 miles on it.
A couple days ago I started noticing a clicking noise near the right-front wheel area whenever I turn for the first time after I start the engine (releasing handbrake, shift to Drive, etc). This happens only one time per drive, and mostly after I turn to the right for the first time. After hearing that sound, the next time I will hear it is only after I park and shutdown the engine and restart.

I just purchased a 2017 Outback. I noticed a rattling noise (like marbles) coming from the engine upon startup in the morning only. The noise goes away after a few seconds. To me it sounds like bearings rattling due to low oil pressure, but the dealer says that every Outback and Legacy does this. It has a timing chain and the engines use 0-20 synthetic oil. Is this normal.

Just purchased a 2008 Subaru Impreza Outback Sport with <60K miles for my son. The car is in great shape (body/interior) EXCEPT it probably needs a "new"/rebuilt engine. It started making a tap-tap-tap noise and the mechanic that looked at it said it was an internal engine noise; that they would not tear apart the engine to determine the cause, but install a rebuilt engine ...

I bought this Subaru used with 350 000 km's on it,and I haven't added that many kilometers to it yet at all. For some reason whenever I drive on the highway and get my speed up to about 120 the front left part of the car (somewhere underneath the hood I believe) starts to make a loud gurgling type of noise. I know that the suspension on that front left tire is missing, but I don't feel the rumbling on my steering wheel and I don't think it's coming from there.

I have a 2006 Outback XT, which recently started shuddering (like it wants to stall) at idle... At least that's how it started. I noticed it for a few weeks but with no check-engine light, and no error codes cropping up, I kind of ignored it. It then started to stall at idle. Took it to my local guy, who checked all the simple stuff: vacuum hoses, mass air flow sensor, he even removed and cleaned up the throttle body. But the problem persists.
I guess the part that really has me puzzled is the lack of a check-engine light or an error code. With how computer-regulated cars are nowadays, I'm baffled as to how this isn't causing some alarm to go off.

My outback has 57k miles on it and already needs the front struts and rack replaced (diagnosed today at the Subaru dealership). The car has been making a whining noise in the engine and has been clunking when making turns for the past week. I have also noticed it hasn't been taking bumps as smoothly. They told me that both ends of the rack are leaking and both front struts are leaking. My husband did admit to hitting the curb on the driver side front tire pretty hard while making a u-turn about a month ago, but all other driving is pretty standard. Yes, we drive on dirt roads in the mountains a few times a year for hiking, but don't drive in a manner that I consider wrong. Did the u-turn incident cause this? (hard to believe that would affect both sides of the rack and struts).

Need to determine the cause of a strange high-pitched squealing noise coming from the engine compartment of my 2008 Subaru Outback 2.5l automatic. The squeal happens only when the temperature is cold (below 32 degrees) AND I hit a bump. It happens more often the colder it is outside. The noise is definitely coming from the front of the car and seems like the passenger side but I can't be sure. It happens with the blower fan/AC both on and off so I don't think it is caused by that. It happens when the car is cold or driven for a while and warmed up.
It occurs at both high & low speeds. I checked all my fluids under the hood and everything is filled as it should be. There are no lights (check engine or ABS) on. Recommend any troubleshooting that I can try? I have not taken it to a mechanic yet as they might have a hard time reproducing the noise since it has to be below freezing and hit a decent bump. I attach a video that I took while driving last week on a 16 degree day and heard the squeal when I hit a bump. I had been driving for about 30 min when it occurred. I have more videos of the noise if needed.

Two weeks ago I bought a new 2012 Outback. While driving in the manual auto mode, the cruise started flashing, the check engine came on, the traction control light came on and the brake light was on. The dealer said it was because I did not tighten the gas cap, letting air in. They reset it but a few days later it came back on again and this time they said it was miss fire code. Since they couldn't figure out the issue, they did the right thing and traded it in for another, identical 2012 Outback. Now, 8 days later, all the same lights have come on.

I have a 2004 Subaru Outback. This fall I started having intermittent problems starting the car. It would run like a champ, no problems. Then every once in a while when I would try to start it, typically happens after it has sat all night, it would turn over just fine, motor would catch, then the motor would quit running (almost immediately upon start). It is kind of like the old days when your carburetor was not adjusted quite right and you would have to keep one foot on the brake the other on the gas while stopped at a stop light to keep the motor running.
The first time it happened we added "heat" as we thought it might be water in the gas line somewhere. It started, then ran just fine. This winter the problem started recurring more frequently. We added injector cleaner, it seemed to work a bit, but did not solve problem. We took it to the shop, and they could not figure out what was going on as nothing is registering on the computer and the car would start just fine for them. Brought the car home it worked OK for a week or so, then started up again.
The motor would catch then would quit running almost immediately. We were able to get it running good enough to get it to the shop (kept one foot on gas at stop lights, etc so would not kill). My car has been at the shop for two weeks now. It finally misbehaved on their watch, and they replaced a sensor, but they are not sure it fixed anything. They are keeping it so see if they can get a better diagnosis.
My first thought was the gas pump, but they said they had never seen a subaru gas pump fail and usually when a pump goes out, it goes out. They thought it could be electrical, but not sure as the problem is so intermittent. I would like to get my car fixed and back home. It's a great car; when it is running it runs great. The shop we work with is very good, and they are reluctant to start just replacing parts if it is not going to fix the problem.

2000 Subaru Outback. The head gaskets have begun to leak slightly (oil and coolant), even though I brought it in for the recall at 80K and the dealer put in the additive. I recently (111,000 miles) put in another bottle of the additive coolant conditioner and the leak seems to have at least slowed to a trickle. Is it really essential to have the head gaskets replaced? Or could I just keep an eye on the oil and coolant levels and put a bit of kitty litter in my garage? Some of the information I googled indicates that the recall of this car is for an OUT leak and not an INNER leak--which would be worse. Is it true that an OUT leak is not as worrisome?
